COMBINED CAN OPENER AND FOOD CAN Filed July 31, 1961 INVENTOR. PETER FAVOLI SE A 770mm 4 United States Patent 3,042,249 COMBINED CAN OPENER AND FOOD CAN Peter Favolise, 356 Asylum St., Norwich, Conn. Filed July 31, 1961, Ser. No. 128,043 9 Claims. (Cl. 220-48) This invention relates to can openers and has as its principal object provision of a can opening blade secured to a beverage can for opening other cans.

The blade is welded to a cylindrical can used for beverages such as beer, juices or the like, and extends radially outwardly and downwardly. One empty can may be disposed adjacent to a filled can and the blade will be pressed downwardly to puncture the top of the filled can. The blade can be formed with a plurality of teeth to cut a pouring opening and provide an air release hole in the top of the can.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure:

FIG. 1 is a perspective view of a can embodying the invention.

-FIG. 2 is a side elevational view partially in section showing two cans according to the invention.

FIG. 3 is a fragmentary perspective view of another can showing another can opener embodying the invention.

FIG. 4 is a top plan view of a can opened by means of the can opener of FIG. 3.

Referring to FIGS. 1 and 2, there is shown a can having a cylindrical body 12 near the top circular bead 14 of which is located a can opening blade 16. This blade has an arcuate flange 18 secured by welding 20 to the can body. The blade is generally triangular and extends radially outwardly of the can and downwardly toward the other end of the can. On the circular top of the can is a triangular hole 26 such as would be formed by the can opening blade 16 of another can. The excess metal defines a triangular flap 28 which is pressed downwardly into the body of the can.

FIG. 2 illustrates how the can opener is used. An empty can 10 is disposed axially parallel to another can 10 containing a beverage 30. The empty can is disposed so that the point or apical end of the blade 16 pierces the top 25' of can 10 to form hole 26'. The downwardly inclined blade 16 cuts the metal of the can top at 28 and presses it toward the inner side of the can to clear the hole 26' for pouring the beverage 30. Can 10' in turn has a can opener blade 16' thereon which can be used for opening a further can, and can 10 can be discarded.

FIG. 3 shows another cutting blade 16* mounted by spot welding 32 at arcuate flange 33 to the cylindrical body 12 of can 10 The blade has two generally triangular cutting teeth 34 and 36. Tooth34 is longer and Wider and forms a triangular hole 35 such as shown on the top 38 of can 10 in FIG. 4. The other tooth 36 is shorter and narrower and forms a small air hole 42 as shown in the top of can 10 In use, the blade of can 10* will be forced down on the top of another can such as can 10 to form the desired beverage pouring hole 35 and air hole 42. If desired, tooth 36 may be applied alone to form other air holes such as shown at 42 and 42 to increase the speed of beverage flow through hole 35. Can 10 in turn has a blade 16 like blade 16 for opening further cans.

The invention provides the advantage that the user always has available a can opener for opening cans as needed. The can opener on each can is always new,

unused and bright. Where one relies upon separate can openers used frequently, there is by contrast, danger of contamination by rust.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and that various changes and modifications may be made within the scope of the invention as defined in the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent is:

1. A can opener comprising a cylindrical can body, a blade having an arcuate flange welded to the can body near one end thereof, said blade being generally triangular with a free apical end extending radially outwardly of the can body and directed toward the other end of the can body, whereby one cylindrical can body may be disposed adjacent to another cylindrical can body and axially parallel therewith, with the apical end of the blade located at the top of the other can body, and whereby axial movement of the one can body with respect to the other can body causes the blade to pierce said top to form a generally triangular hole with excess metal of the top forced downwardly into the other can body to clear said triangular hole.

2. A can opener comprising a cylindrical can body, a blade having an arcuate flange secured to the can body near one end thereof, said blade having two generally triangular teeth with free apical ends of the teeth extending radially outwardly of the can body and directed toward the other end of the can body.

3. A can opener comprising a cylindrical can body, a blade having an arcuate flange secured to the can body near one end thereof, said blade having two generally triangular teeth with free apical ends of the teeth extending radially outwardly of the can body and directed toward the other end of the can body, one of the teeth being longer and wider than the other tooth to form a beverage pouring hole in the top of another can while the other tooth forms an air hole in said top of the other can.

4. A can opener comprising a cylindrical can body, a blade having an arcuate flange secured to the can body near one end thereof, said blade having two generally triangular teeth with free apical ends of the teeth extending radially outwardly of the can body and directed toward the other end of the can body, one of the teeth being longer and wider than the other tooth to form a beverage pouring hole in the top of another can while the other tooth forms an air hole in said top of the other can, said flange being secured by welding to the can body, whereby one can body may be disposed adjacent to another cylindrical can body and axially parallel therewith, with the apical end of the longer and wider blade located at the top of the other can body, and whereby axial movement of the one can body with respect to the other can body causes first the longer and wider tooth to pierce said top to form a generally triangular hole with excess metal forced downwardly into the other can body to clear said hole, and then the shorter and narrower tooth pierces the top of the other can at a point spaced from said hole to provide an air hole thereat.

5. A can opener comprising a cylindrical can body, a generally triangular blade having its wider end secured to the can body near one end of said body, said blade having its apical end extending radially outwardly and downwardly from the can body and directed toward the other end of said can body.

6. A can opener comprising a cylindrical can body, a blade having one end secured to the can body near one end of the body, said blade having a plurality of teeth of dilferent size extending outwardly and downwardly from the can body and directed toward the other end of said can body.

7. A can opener comprising a cylindrical can body, a blade having one end secured to the can body near one end of the body, said blade having a plurality of teeth of different size extending outwardly and downwardly from the can body and directed toward the other end of said can body, said teeth each being generally triangular in form.

8. A can opener comprising a cylindrical can body, a blade having one end secured to the can body near one end of the body, said blade having a plurality of teeth of different size extending outwardly and downwardly from the can body and directed toward the other end of said can body, said teeth each being generally triangular in form, said one end of the blade being secured by welding to the can body.

9. A can opener comprising a cylindrical can body, a generally triangular blade having its wider end secured to the can body near one end of said body, said blade having its apical end extending radially outwardly and down wardly from the can body and directed toward the other end of said can body, said blade having its wider end secured by welding to the can body.
